ANTIFREEZING-TANK.

Specification of Letters Patent.

Patented May 10, 1910.

Application filed June 10, 1909. Serial No. 501,362.

To all whom it may concern:

Be it known that I, LEONARD HnIsnL, a citizen of the United States,residing at Fremont, in the county of Mahaska and State of Iowa, haveinvented a new and usefu Improvement in Antifreezing- Tanks, of whichthe following is a specification.

This invention relates to watering troughs, and especially to a troughdesigned for watering hogs, and the object of the invention is a troughin which the water is automatically held at the desired level, and whichis protected so that the water in the trough will not freeze during thewinter.

I am aware of the fact that a number of automatic troughs have beenplaced upon the market but I have found by experimenting with a numberof them that they would not operate in cold weather owing to thefreezing of the water, which of course prevented the mechanismregulating the flow of water from operating and I have also found thatit is practically impossible in a watering trough for hogs to preventthe accumulation of a certain amount of mud in the trough and this alsofrequently clogs some part of the mechanism designed to regulate theflow of water.

The object of my invention is to overcome these disadvantages andthereby insure the steady operation of the device.

My invention consists of the novel features of construction hereinafterdescribed, pointed out in the claim and shown in the accompanyingdrawings, in which,

Figure 1 is a perspective view of my device. Fig. 2 is a verticalsection.

V In these drawings 1 represents a suitable tank or reservoir in which asupply of drinking water is kept and which may be filled in any desiredmanner. Located. adjacent this tank is a drinking tank 2, the endopposite the tank being open as shown at 3 so that the stock to bewatered can gain access at any time to the water in the trough. Theremainder of the trough is covered as shown at 4. A pipe 5 connects thetank and trough extending part way into each and being angled upwardlyat its inner end, that is within the tank 1. A suitable valve 6 ismounted upon an upwardly angled inner end portion of a pivoted rod 8 andis adapted to seat upon and close the upper inner end of the pipe 5. Toprevent sediment from accumulating beneath the valve 6 and interferingwith its operation it is protected by an inclosing screen 7. The rod 8is pivoted within the pipe 5 and at a point nearest the inner end so asto allow for an increased leverage and movement of a float 9 carried bythe outer upwardly angled portion of the rod, which float rises andfalls with the water level in the trough. Then the water level reachesits predetermined height thus bringing the float 9 to its highest pointthe outer end of the rod 8 is lifted and the inner end depressed thusdrawing the valve 6 downwardly and closing the inner end of the pipe 5.tank 2 the corresponding fall of the float 9 will lift the valve 6 thusadmitting an addi tional supply of water to the trough. To prevent theaccumulation of mud into the covered portion of the trough and beneaththe float 9 a transverse partition 10 of any desirable height is placedin the trough and substantially in vertical alinement with the rear edgeof the open portion of the trough.

The partition 10 serves as a stop to pre vent mud from passing to therear end of the trough and the protecting cover 4. which extends overthe greater portion of the trough prevents the freezing of the wateraround the float 9, which would of course interfere with its operation.I have found by experience that a tank and trough constructed as hereinshown and described can be operated in the State of Iowa during thewinter time without the formation of ice in the trough to a suflicientextent to interfere with its operation, while during the same period oftime troughs not so protected would become useless owing to the freezingof the water in them.

WVhat I claim is V The combination with a tank, of a trough, a coverextending over the greater portion of the trough, a pipe connecting saidcovered portion with the tank, a transverse partition arrangedsubstantially in vertical alinement with the front end of the coveredportion, said partition being of less height than the trough, the saidpipe having its inner end portion upwardly angled, a rod pivotallymounted in said pipe having upturned end portions, a valve carried bythe inner end of the rod, and a float carried by the outer end.
